Brief Description

Agent.IWB is a backdoor that allows hackers to gain remote access to the affected computer in order to carry out actions that compromise user confidentiality and impede the tasks performed on the computer.

It uses stealth techniques to avoid being detected by the user:

It injects itself in running processes.

It deletes the original file from which it was run once it is installed on the computer.

It uses several methods in order to avoid detection by antivirus companies:

It terminates its own execution if it detects that it is being executed in a virtual machine environment, such as VMWare or VirtualPC.

Agent.IWB does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.
